Our milkman, whom we've never met as they deliver our milk early hours, left us a Christmas card personalised with our family name with last week's delivery. I went to leave a card and tip on door step in plastic sleeve, under rock for them. The milkman usually comes around 1am. They are very reliable. Anyway, at 4am I get up to let cat out and see no milk and card still there so as its raining take it back in and assume milk not coming. Milkman turned up around 5am. So didn't get card. I don't know why it upset me so much but feel guilty I didn't respond to their card and worry they think we are scrooge for no card/tipping. Would it be OK to put card there with tip after Christmas as in near new year or is that strange?
AIBU to feel guilt for such thing and should I leave it out after Christmas
